Safety
10|2018 EN 11
2.7.4 Hot surfaces
The electric motor can reach temperatures of up to 70 °C. There
is a risk of being burned.

Do not touch the motor during operation.
 Allow the pump/unit to cool down before servicing it.
2.7.5 Hazardous materials
 Ensure that leaks of dangerous pumped fluids/gases are led
away without endangering people or the environment.
 Decontaminate the pump completely during disassembly.
2.7.6 Suction danger
Ensure that the suction openings conform to current guidelines,
standards and instructions.
2.8 Faults
 In case of a fault, immediately switch the pump off and
remove it from operation.
 Have all faults repaired immediately.
Seized pump
If a pump seizes, and is switched on several times repeatedly, the
motor can be damaged. Observe the following points:
 Do not switch the pump/unit on repeatedly.
 Turn the motor shaft by hand. See point 6.1.2 on page 22.
 Clean pump.
2.9 Preventing material damage
2.9.1 Leakage and pipe breakage
Vibrations and thermal expansion can cause pipes to break.

Install the pump/unit in a manner which reduces structure-
borne and airborne noise transmission. When doing so,
observe relevant regulations.
If the pipe forces are exceeded, leaks can occur at the screwed
connection or the pump itself.
 Do not use the pump as a fixed point for the pipe line.
 Connect pipes free of load and mount them elastically. Install
compensators if necessary.
 If the pump leaks, the unit may not be operated and must be
disconnected from the mains power supply.
